SASH OPERATOR AND FASTENER.

Application filed March 26, 1924. Serial No. 701,966.

To all 41:7 am may concern:

Be it known that I, RICHARD A'rKINsoN Invmc, a subject of the King of Great Britainand Ireland, residing at Gateshead, in the county 01' Durham, England, have invented certain new and useful Improvements in Sash Operators and Fasteners, of which the following is a specification, reterenee being had therein to the accompanying drawing.

This invention relates to sash operators and fasteners for windows and the like having vertically sliding sashes, and has for its object to provide improved devices whereby the upper sash can be lowered and raised by the movement of the lower sash and whereby the two sashes can be locked together either in the fully closed position or with one or both sashes partly open.

Devices in accordance with my invention comprise in combination a spring-pressed belt of known type on the lower sash coacting with a pair of special socket memhers on the upper sash disposed vertically one above the other. The belt is capable of being fixed, when desired, in a position intermediate of its fully retracted and its fully projected positions. The upper of said special socket members has a rising track leading from below to the lower edge of the socket therein which lower edge is of such depth that it is cleared by the bolt in its intermediate position but is engaged by the bolt in its fully projected position, and the upper edge of said socket being of such depth that it is engaged by the'bolt in its intermediate and in its fully projected positions. In use, when the lower sash is raised with the bolt in its fully projected position, the bolt rides up the rising track of the upper socket member and engages infthe socket therein whereupon theuppersash can be lowered by pulling down the lower sash.

lVhen the upper sash has been lowered and it is desiredto again raise 1t, the bolt is set;

in its intermediate position and the lower sash raised until the bolt coacts with the upper edge of the socket in the upper socket,

member, and the bolt then carries the upper sash up withthe lower sash.' When the lower, sash is again pulled down, the. bolt clears the lower edge of the socket and leaves the upper sash in its raised position. The lower socket on the upper sash is disposed so as to be in alignment with the bolt when the sashes are in the i'ully closed position,

the sashes being locked in this position by v projectingthe bolt into said socket. A supplementary socket is provided a short distance above the lower socket whereby the sashes may be locked when the lower sash is slightly raised or the upper sash isslightly lowered or when both sashes are slightly open, which supplementary socket may also be used to lower or raise the upper sash a short distance. y v r The accompanymg drawings illustrate sash devices in accordance with my invention as applied to the sashes of a windows In the drawings, Figures 1 and 2 areelevations at right angles, only somuch of the window sashes being shown asis necessary to illustrate the arrangement of my devices; Figures 3 and 4 are sectional elevations of the spring bolt in engagement with the the rear end of the barrel. The plug is slotted atrl'l' so that the bolt is free to slide therethrough only when said projections are in alignment with said slot., By retracting the bolt against the action of its spring and slightly rotating it, the projections are moved out of alignment with the slot, and the bolt can be temporarily fixed in the fully retracted position by engaging the projection 1% with the end of the position intermediate of the fully retracted and the fully projected positions by engaging the projection 15 'with the end of the plug 16. A segmental track 18 in the end of the plug facilitates the rotary adjustment of the bolt 11. The operativeend of the bolt is preferably provided with a small ball 1.), and the rear-end of the bolt is fitted with a knob 20 whereby it can'be operated.- The spring 13 within the barrel bears between a washer 21 bearing on ashoulder 22 around the bolt andthe inner end of the plug 16. 1

, To the face of one of the side bars 2-3 of the upper sash near the top thereof I at tach an upper socket member 24 which is, provided with a rising track 25 leading to plug, or in a ill) thelower edge of a socket 26, which lower edge is of less depththan the upper edge 27 thereof. One side of'the socket member 24 is formed to suit. the curvature of the sash bar 23 to which it is attachedby screws 28. The member 2a is also provided with a laterally-projecting finger Piece 29.

At the bottom of the side bar 23 of the upper sash I mount a lower socket member 30 having a socket 31 and preferably also a supplementary socket 32 to which lead risingtracks33, 3% the distance between the sockets 31 and 32 being chosen as that at which it is convenient to lock the sashes in a slightly open position. The depth -01": the lower edge of the socket'32 is less than that of its upper edge so that the bolt 11, when in its intermediateposition, clears the lower edge of the socket 32.

In use,- the upper socket member 24 is at-v tach'ed to the side bar 23 with its rising track '25 vertical as shown, and the lower socket member 30 is attached tothe bar 23 vertically below the upper member 24 so that its sockets 31, 32 are in vertical alignment with the socket 26. The bolt 11 is attached to the upper rail 10 of the lower sash so as to project horizontally in vertical alignment with the sockets 26, 31 and '32, the socket 31 being in horizontal alignment with the bolt 11 when the sashes are closed.

When the bolt 11 is in its fully retracted position, as indicated in Fig. i, the sashes are freely slidable. When the bolt is in its intermediate projectedposition, as shown in Fig. 3, it clears the lower edges ofthe sockets 26 and 32 but engages the upper edges thereof. hen. the bolt is fully projected, as shown in Fig. 1, it will engage and lock itself in any of the three sockets.

To operate the uppersash by means of the lower "sash, if the upper sash is in its normal raised position and it isdesired-to lower it, the bolt 11 is set in its fully projected position after the sash has been raised to bring the bolt above the socket 32, and the lower sash is then further raised until the bolt engages the socket 26, the bolt riding there into up the track 25. The lower sash is then pulled down bringing the upper sash with it. It the upper sash has been lowered and it is desired to raise it, the bolt is set in its intermediateposition and the lower sash raised until the bolt engages the upper edge 27 of the socket '26 when "further raising oi": the lower sash raises the upper sash. The lower sash can be lowered again without aiiectin-g the upper sash, the bolt clearing theloweredge of the socket 26. The linger piece 29 provides a means for raising or lowering the upper sash independently of the bolt 11. When itis desired to lower or raise the upper sash only a short distance, the socket 32 is'usedinstead ot' the socket 26.

The sashes can be locked in the closed position by projecting the bolt 11 intoengagement with the socket 31 as shown in Fig. 1, or locked in a slightly open position by engaging the bolt with the socket 32.

lVhile I have illustrated the bolt 11 and socket members 2% and 30 as applied to the right hand side of a window it will be understood that they can be readily adapted for application to theleft hand side of a window. Alternatively, the socket member's may be attached to either side of the centre bar of the window, where such exists, and thebolt correspondingly disposed'on the top bar of the lower sash. Where a window sash is provided with a horizontal cross bar 35, a bridgepiece 36 having a double rising track '37 is mounted as shown in Fig. 6 on the side bar 23, or centre bar, in the vertical path of the bolt 11, said track engaging the operative end of the bolt and guiding it over thecrossbar.

What I claim as my invention and desire to secure by Letters Patent is 1. Sash operating 'devices for windows comprising the combination of a horizontally disposed barrel adapted to be mounted on the lower sash of the window, a spring-pressed bolt therein, and means for temporarily fixing said bolt in any one of three positions, namely a fully projected position, an intermediate position and a fully retracted position, and a socket member, adapted to be mounted near the top of the upper sash of the window, said memher having a socket which can be disposed in vertical alignment with said bolt, the lower edge of said socket being of such depth that it is cleared by the bolt in its in termediate posit-ion but is engaged by the bolt in its fully projected position, and the upper end of said socketbeing of such depth that it is engaged by the bolt in its inter- Inediate-and-in its fully projected positions, and a rising track leading from below to said lower edge.

2. Sash operating and locking devices for windows comprising'the combination of a horizontally disposed 'hari'el adapted to be mounted on'the lower sash of the window, a spring-pressed bolt'therein, and means for temporarily fixing said bolt in any one of three positions, namely a fully projected position, an intermediate position and a fully retracted position, a socketmember adapted to be mounted near the top of the upper sash of the window, said member having a socket which can be disposed in vertical' alignment with said bolt, the lower edge of said socket being of such depth that it is cleared by the bolt in its inter mediate position but is engaged by the bolt in its i ullyprojcctedposition,and the upper edge'oi said socket being of such depth that it is engaged by the bolt in its intermediate and in its fully projected positions, and a rising track leading from below to said lower edge, and a second. socket member adapted to be mounted at the bottom of the upper sash of the window, said member having a socket therein which can be disposed in vertical and horizontal alignment with the bolt when the sashes are in the closed position, and a supplementary socket disposed a short distance vertically above said lowermost socket, the lower edge of said supplementary socket being of such depth that it is cleared by the bolt in its intermediate position but is engaged by the bolt in its fully projected position, and the upper edge of said supplementary socket being of such depth that it is engaged by the bolt in its intermediate and in its fully projected positions, and said supplementary socket having rising tracks leading from above to its upper edgeand from below to its lower 20 edge; I

In testimony whereof, I afiix my signature.
